Application filed November 23, 1912. Serial No. 733,224. a

terial injury by contact with stones and other unyielding substances.

Another object is to provide a the, the parts of which can be assembled readily and will not easily get out of order.

lVit-h theforegoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of What is claimed, without departing fronrthe spirit of the invention. In the accompanying drawings the preferred form of the invention has been shown. In said drawingsz Figur-e 1 is a. view partly in side elevation and partly in sec tion of aportion of a wheel having the present improvements combined therewith. Fig.

2 is a section online A-B Fig. 1. Fig. 3 is an enlarged section through a portion of the tire, said section being taken on the line (3-D Fig. 2. Fig. a is a section through the inner ring of the tire said sec tion being taken on the line E-F Fig. 2.

Referring to the figures by characters of reference 1 designates the :rim of the wheel, the same being provided,lupon:both sides, with retaining rings 2 each of which is preferably formed of a flat strip secured to the rim preferably by means of bolts 3 which extend transversely. through both'of the rings 2.

Interposed between the peripheral portions of the retainingrings 2 is a tubular metallic outer ring 4 preferably rectangular in cross sectional contour, this outer ring being secured fixedly to the retaining rings 2 by transversely extending bolts 5. Formed in the sides of the outer ring 4 at points midway between the bolts 5, are transverse depressions 6 within which arms 7 are n'lounted to move freely. These arms are arranged radially and are seated at their in nor ends within recesses 8 formed in the Sides of the Inner metallic ring 9 of the tire.

This ring 9 is 'n'e't'crably Ftubular and rectangular ll) cross scctlonal contour, said ring extending entirely around the wheel and being spaced from thernn 1 by an inner cushioning ring 10 of rubber \\'lll(.ll complelely fills the space between the ring 9 and the rim 1. As shown in Fig.2, this ring 9 15 preferably formed Wllll channels within its inner and outer faces, as shown at 11 and 12, the cushioning ring 10 projecting into the inner channel 11 so as thus tobe held against lateral displacement relative to the inner ring 9. The arms 7 are secured to the ring 5) by bollslt-B extending transversely through the ring, said ring being prcfi-n'ably reinforced at the points where the bolts are received, as by extending sleeves ll transversely within the ring nd through which the bolts 13 project. 'lhcse sleeves are preferably integral with the ring as shown in Fig. 4.

Interposcd between the outer metallic ring 4 and the inner ring 9 is an outer cushioning ring 15 of rubber or the like, this ring being engaged within the outer channel 12 in the ring 5). As the. ring l is fixedly connected to the rim 1 by the retaining rings 2, it will'be apparent that it thus becomes impossible for the ring 9 to shift inwardly or outwardly without compressing portions of one or the other of the cushioning rings 10 and 15.

The arms 'ZQ as hcreinbcfore stated; are adapted to move freely within the recesses formed in the outer metallicming 4. The

outer ends of the arms 7 are pivotally connected to brackets 16. These brackets 16 wheel. Each tread plate has one half thereshown. a

' 'Aswill be noted particular y byjreferrinfg to Fig, 2,;the arms 7 of each pair are pre erably formed integral with a crossjlpin which extends through and is adapted to ro-' tate within one of the brackets 16.

' a It will .be noted; that; by connecting the treadplates to 'thefinner-ring 9 by means of theradia'larms 7-, fsa id treadplates are held "ing said rin to compress a portion of the cushioning ring 10.
